Mano Menezes looks set to call on his strongest side for the important clash against La Tri. The Selecao coach started with Jadson ahead of Robinho against Paraguay, yet it is unknown if he will follow the same route. Tottenham midfielder Sandro has also withdrawn from the squad, citing a knee injury. Having seen rivals Argentina qualify in their final group game, the five-time world champions know that only a much-improved display will see them progress.

Reinaldo Rueda is again without Manchester United winger Antonio Valencia, who picked up an ankle injury in the first match against Paraguay and the coach has maintained that he will not be risked. Otherwise, Ecuador remain unchanged. They are also in contention for a place in the last eight, but only if they overcome the defending champions.

DID YOU KNOW?

Brazil are the defending champions of the Copa America, having won in Venezuela in 2007.

The Selecao however, are still not assured of a quarter-final place, and will only qualify for the last eight if they do not lose to Ecuador.

Brazil have only lost once to Ecuador in seven previous encounters.

Mano Menezes' men needed a late Fred equaliser to salvage a draw against Paraguay on Saturday. The unconvincing result leaves them 3rd in Group B, level on points with Paraguay and one behind leaders Venezuela.

Ecuador are draw specialists of late, with Rueda's side on a run of six straight ties in 2011 before last weekend.

La Tri's 1-0 defeat to Venezuela thanks to a stunning Cesar Gonzalez strike has seen Rueda's side sit bottom of Group B. Nevertheless, the Ecuadorians are stlll in contention to qualify if they beat Mano Menezes' men in Cordoba.

Ecuador are winless in eight consecutive games. Their previous victory came in a 4-1 thrashing of Venezuela, whom they were defeated by in their last game.

Ecuador held Brazil to a 1-1 draw in their last head-to-head meeting, with Christian Noboa striking in the 89th minute to deny the Selecao in 2009.
